APPARATUS FOR CARBURETING AIR OR GASES.

SPECIFICATION forming part of Letters Patent No. 308,886, dated December9, 1884.

Application tiled Jtly 10, 1884. (No model.)

To all whom it may concern.-

Be it known that I, ANDREW J. ENGLISH, a citizen of the United States,residing at Oincinnati, Ohio, have invented new and useful Improvementsin Apparatus for Carbureting Air or Gases for Illuminating Purposes, ofwhich the following is a specification.

My invention relates to that class of gasmachines in which atmosphericair or gas is forced through suitably-arranged carburetingchambers incontact with a volatile hydrocarbon liquid,with a view to the saturationof the gas with the hydrocarbon vapors, to be used for domestic,industrial, or illuminating purposes, and it consists, first, in theconautomatic supply of liquid to the carburetingchambers as needed, and,second, in the provision and arrangement of means for indicating theexhaustion of liquid from the supply 19 p, the inflow and outflow airpipes; It, the

reservoir; 1), the overflow-pipes between the carbureting-chambers,these parts beingconstrueted and arranged in the usual manner, and thechambers being channeled and provided with absorbent material (not shownin the drawing) to assist evaporation.

3 5 To secure the automatic feeding of the chambers c"a a, I place inthe bottom B of the reservoir R a valveseat and opening, 0, controlledby a lift-valve, o, the latter connected by rods r r and a pivotedconnecting-lever, Z,

with a float, f, arranged in the lower carbureting-chamber, a. The leverZ is mounted upon a suitable supporting-frame, c, or it may be hung fromtop of the reservoir It, and the rod 1' is carried down through an opentube, t,

i 5 passing from a point above the highest level of the liquid in thereservoir B into the lower chamber, a, through theseparating-partitions. The construction is clearly shown in the drawing,and the float f should be of sufficient Weight to elevate the valve withcertainty.

struction and arrangement of means for the against any tendency of thelatter to stick from any cause, yet to rise with the liquid and closethe valve when the proper level is attained.

It will be apparent that as the greatest consumption of liquid takesplace in the lower chamber,where the air or gas is first admitted, andas the chambers are furnished with overflow-pipes,the feeding will takeplace continuously as long as any liquid remains in the upper chamber,R-that is, a very slight diminution of liquid in the lower chamber,a,will allow the floatf to fall, which, acting by its weight on the rod9 and lever Z, will lift the valve 1; from its seat, allowing the liquidto flow into chamber a thence, when the top of the overllowpipe 1) isreached, into the chamber a, and similarly, by pipe 133 therein, intothe chamber a, where equilibrium will be es" tablished by the raising ofthe float f and con- '70 sequent closing of valve t. It will thus beseen that as a slight lowering of liquid in chamber a is accompanied byalesser lowering in chamber a, and one still less in chamber a, thequantities of liquid contained in 7 5 the several chambers will bear aconstant relation to each othersuch that as long as any liquid remainsin the upper chamber the valve 1) will deliver it continuously and injust the 7 quantity required for consumption. 30

To determine when the chamber R becomes nearly empty, I provide a tube,t, (through which rod 1-", carrying the float f, passes,) and which alsopasses through the horizontal partitions b of the carbureting-chambers aa a 8 5 and, furnishing communication between the top of the upperreservoir, R, and the top of the lower chamber, a, acting also as a ventand allowing ready escape of liquid through valve '0 by equalizingpressure. Two test- 0 pipes, w 20 are also provided, issuing from theside of reservoir R, near the bottom, but at different heights, andprovided with whistles or similar devices, 5/, at their upper ends, andclosed by capscrews. Upon unscrewing 5 the cap a from tube w, should thelevel of liquid in reservoir B have fallen below the opening 8, the airor gas entering at p in lower 7 chamber, a, will pass by means of pipe25 to the reservoir R, and thence out through pipe 10, giving warning byblowing the whistle g. A similar test may be made with the pipe 10 whichwill in turn indicate the fact, should the level of liquid in R be belowthe orifice s, when the reservoir R will be empty.

A supply-pipe, S, furnishes the means of filling the empty reservoir,and may also serve as a test-pipe, when provided at the top with lateralbranch pipe and whistle 9, closed ordinarily by a cap. If the reservoirbe empty, on unscrewing the cap the whistle sounds. The vent-pipegallows air to escape while filling the reservoir.

To provide for the escape of water condenschamber a, oil-supplyreservoir R, and test ing in the gas or'air supply pipe 1), I provide inthe latter an outlet-pipe, p, with a cock, K, and a smallcollecting-chamber, O, at or near the entrance to the chamber a, communicating with the open air. On opening the cock at intervals anymoisture will be eX- pellcd.

I claim as my invention and desire to secure by Letters Patent of theUnited States 1. In'agas-carburcfing machine embodying a reservoirarranged above a series of carbureting chambers, the latter providedwith short overflow-pipes connecting the chambers, the lower chamberbeing the air or gas entry, the float f in the lower chamber, the rod 0,connecting the float and a lever, Z, through the open tube 1;, (saidlever being pivoted to said rod,) the lever l carrying pivoted at oneend the float-rod 1- and at the other end the valve-actuating rod r, andbeing pivotally supported at an intermediate point in the oil-- fixed tothe conical valve 1), seated in the bottom of the reservoir, andsurrounded by suitable protecting netting, the open tube 25, furnishingfree air or gas communication between the lower chamber, a", and the oilsupply chamber It, and surrounding the float-rod 1"", the wholecombined, arranged, and operating as and for the purpose specified.

2. In a carburetor having an oil-reservoir above a series ofcarbureting-chambers con nected in series, a pipe, t, surrounding thefloat-rod T and providing air communication between the oil-reservoirand lower air-entry chamber, in combination with the ainentry tubes 20 w(one or more,) having attached above whistles or call-indicators {1,actuated by the passage of gas outward therein, said tubes entering thelower chamber at different heights, substantially as described.

3. In a carburetor having an oil-reservoir above a series ofcarburetirig-chambers connected in series, and with tube t, connectingthe top of oil-reservoir and lower air-entry chamber, the combination ofoil-reservoir It, tube 16, air-entry chamber (1., air-pipe p, and theenlarged chamber at or near the air-entry point on the air sup fly-pipeprovided with outlet'pipe p, stop-cock l1", and a manipulating-handleextending upward, arranged and o1i erating substantial] y as set forth.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing wit- DQSSGS.
